Reported Burn In Rates as of 24 Jan 2019
2018 OLEDs - 1.9% (out of 108 votes)
2017 OLEDs - 7% (out of 201 votes)
2016 OLEDs - 28.7% (out of 216 votes)
2015 OLEDs - 12% (out of 22 votes)
Notes on the Results so Far....
2018 Panels - one user reported faint burn in and that they use their 2018 OLED for very long hours and as a "PC monitor, for gaming, movies and TV - so lot's of static stuff on screen especially when using as a PC monitor or playing games for hours at a time"
2017 Panels - 14 users have reported burn in. One of these cases was apparently due to HDR gaming on a Philips OLED. This is an interesting case.
2016 Panels - More than 1 in 4 owners have reported burn-in! In this poll, the rate of burn in for 2016 OLEDs is much higher than than for 2017 OLEDs.
This could
simply be due to burn in being directly related to hours used which is related to panel age. Based on the assumption that the vast majority of panels of a given model year were sold between April and April and that they sold at a roughly constant rate throughout that 12 month period then the average 2016 panel is 27 months old and the average 2017 panel is 15 months old. Perhaps the owners of 2017 panels with burn in are more likely to be those who use their panel for more hours per day.
Alternatively, the difference in burn in rates between 2016 and 2017 panels could be evidence that the 2017 OLEDs are more resistant to burn in. This is possible, as often burn in on 2016 panels seems to be related to the red sub-pixel. The 2017 panels have larger red-sub pixels than the 2016 panels. All other things being equal a larger sub pixel should last longer. This is simply because a smaller sub-pixel has to be brighter per unit of area to generate the same total amount of light. Additionally, we do not know if LG use different OLED emitter compounds in 2017 that could have longer lifespans. (There ongoing R&D aimed at producing OLED componds that are both brighter and longer lasting.)
2015 Panels - lower reported burn in rates than 2016 OLED but with only 22 votes it is hard to draw any firm conclusions.
